# Flexiv Rizon 4

Hardware · `Rizon 4` · verification: source checked

The Rizon 4 is a seven-axis adaptive robot arm with a 4 kg payload and an 876 mm reach, built around industrial-grade force control rather than position control alone. It combines joint torque sensing with vision so it can perform contact tasks such as assembly and surface work. The arm can be mounted at any angle and is rated IP65 for use in dusty or wet environments.
